NEWS LETTER 

BULLETIN NO. 2 
DOUGLAS FIR SEED SOURCES 
The parentage of tree seed and the environment in 
which it is borne greatly influence the quality and rate of 
growth of all planted forests. Because of this fact, MANNING 
SEED COMPANY has enlarged its collection area to supply seed 
from high quality trees in a variety of situations in order 
to better meet the requirements of our customers. 
To insure the integrity of every seed source, our 
seed has been collected and carefully processed under the di- 
rect supervision of technically trained foresters. Each lot 
of seed is positively identified with the area from which it 
was collected so that we can duplicate future collections at 
your request. 
We suggest that you follow two principles of sound 
management in purchasing seed for reforesting your land: 
1. Play safe by using seed from a climatic environ- 
ment similar to the area to be reforested. 
2. Experiment with seed from other environments in 
an attempt to introduce better trees of faster 
growth. 
We have seed on hand from the locations listed on 
the attached sheet. Each locality is coded by a system that 
is based on seed zones as designated by the Pacific Northwest 
Forest and Range Experiment Station and Published by Leo A. 
Isaac of that station in his bulletin "Better Douglas-fir 
Forests from Better Seed".
